GATHARINES, ONTARIO,

CANADA SEPARABLE FASTENER Application filed January 17, 1927. Serial No. 161,628.

The principal objects of the invention are, to produce a stringer on which are secured the individual interlocking members of a separable fastener, which will be uniformly strong throughout its entire lengthtoholdthe interlocking members securely and to retain its shape to keep the individual interlocking member in proper alignment, and to devise a stringer preferably in the form of a bra1d which will be completed in one operatlon.

In carrying out the invention the body of inal ribs are formed along one edge of each stringer, these ribs being opposite each other and on opposite sides of the stringer. The rlbs are formed by forming tubular pockets in which are introduced, as the stringer is fabricated, stuffers of the desired quality to assure the proper securing of the fastener elements. The side ribs are preferably re-enforced by an intermediate rib between the side ribs.

In the accompanying drawings, Figure 1 is an elevational view of pieces of braid showing application to a separable fastener.

Figure 2 is an enlarged exaggerated perspective view of a piece of braid showing a metallic fastener member secured thereto.

Figure 3 is a plan diagram of the surface plateof a braider member designed for manufacturing my improved braid.

Figure 4 is'a plan diagram of a modified arrangement of braider. v

Figure 5 is an exaggerated sectional view of a braid constructed on the latter form of machine.

In the manufacture of what is known as a separable fastener, a braid is used which has a beaded edge and the individual fastener members are secured to this beaded edge and must retain alignment with each other, con sequently the beads which are arranged on both sides of the braid must be uniform and strong.

In the manufacture of this tvpe of fastener it has been the practice :to secure a pair of cords, one on each side of the braid by stitching same to the braid. This is a very expensive operation and more or less uncertain in regard to the location of the stitching through the cords. In the present invention preferably terminating near the vertical axis of the circular arrangement of grooves. The guide groove F is arranged in advance of the circular guide groove D and is operatively connected therewith by guide grooves E and G at each side of the line of guide grooves.

The carriers of ordinary braider type travel in the paths indicated by the arrows from the I circle O around to the circle D. Meshing with D at the point 0 on to the circle E, and the carrier moving along the circle E is transferred at m to the circle F and from the circle F transferred across at o to the circle G and along the circle G back to the circle D from whence it travels back around the orbit of the interlacing grooves of the cam plate.

Mounted in the circles G and E are carriers of ordinary braider type which alternate with the carriers coming from the circle D. The carrier X travelling around the circle E is picked up at the point of intersection 0 with the circle D and following the direction of rotation of the gear of the circle D is carried along the circle D to the circle G where it is picked up at the point m and carried around the circle G, being picked up at the point 0 by the circle F and passed along I the circle F to the point of intersection with the circle E and transferred'back to the circle E.

It will be readily understood from this description with a set of carriers circulating around the two circles E and G across the main line of the braid grooves between the icircles D and F by way of said circlesl) and F, and alternating with carriers inithe main line of braid grooves passin from the circle D to and around the circle and returnin tothe circle D by way of the circles E'and that there will be an interlacing o'fthe threads such a manner as to form pockets'at each side of. the main fabric made up of loopse I u this latter stuifer is not desired to betas hea I as those in the loops formed by the circles a p and G. Such stufiers areclearly illustrated at the ends of'the series of loopsor pockets I e gandf'inFigfip a a n L e braiding of the threads aroundthe arallelly arranged stufiers in themanner; described produces a braid with a pair of op:

G: i :These'fastener members are spaced uniformlyapar't on" the braid'and grip the ribbed edgeof the braid securely and the braided irib: as described retains a straight longitudinal edge which holdsall the fasteners in proper alignment.

(Fu V her,thef ribswhen braided in tothe fabric have the maximum of stre h and as-they are formed in the braiding operation I no further handlingbf thebraid or of any (other materialis required between the con-- fstructionof'the' braid and the application. of

f In" this diagram .thec'arriers passing from the loopJ are carried partly around the loop and transferredto the loop L and being carried partly around the loop L are transferredto the loopM which. carries them yaround three-quarters of a circle and trans: fers to the loopN. It then transfers to K and from K the carriers are transferredto the loop and from 0 they pass to P which conducts themback to N and from N they are passed to M which transfers to Lo and, from L to K, K to N; N-to P and looping around a P are picked up by O, transferredto K and back to J in the direction opposite to the comrnenc'ement.v H.
